First of all, I'm sure this information is on here somewhere... but I sure couldn't find it (google didn't help me, either).

I am going to a bookstore tomorrow to check out the PRS-505 in person and I want to bring a memory stick with some eBooks and Manga to test out on it. The thing is, I don't know where the 505 wants the files. I am using a memory stick from my PSP, so it is FAT-16 right now. I imagine that is fine for the 505, but what about folder structure? I know the PSP was a bit picky about this kind of stuff, but it is better now (for example, a "Music" folder will now show up in the music app, but it didn't always work that way).

Thanks for the help! I also tried using Calibre to transfer files to the memory stick (mounted from said PSP), but it isn't recognizing it as a device.

EDIT: Forgot to mention I use a Mac, so I can't use Sony's software.
